2 Bottom Plow,
The linked pic shows a JD Sub Compact pulling 2 10" plows at what looks to me to be about 4" deep.
Some things to remember:
Wes made some good points about the JD tractor's capabilities.
2 10 inch plows at 4" deep is a hell of a lot different than one 10" or 12" at 6-8" deep.
1100# of GT will not consistantly pull 2 bottoms over 6" in width in ALL soil types.......if you think you've got a winner, bring it over to our farm...we'll just see. Now lighter soils may allow you some room to work, but get in some hard stuff and you'll run out of "a$$" real fast with the typical GT.
You mess with your vertical line of draft with a 2 bottom as well. The further back you put the center of load, the less tractor weight the plow will automatically transfer to the ground........you loose traction and need more weight. Ever notice how nice a 10" Brinly sleeve hitch plow can be made to run, even compared to some of the Cat 0 stuff? I believe that is bacause it achieves close to the optimum vertical line of draft.
I have seen several 6" 2 bottoms, the one I saw in operation seemed to work well under reasonable conditions at moderate depths...and for what it was, made a good showing.
I would personally rather have a single 10" or 12", set to plow at least 6" deep, and cutting a nice furrow......bet you'd get more done better with that rig than a 2 bottom behind a GT.
That said.......2 bottoms done right, to scale, and clean are some of the neatest little GT attachments I have seen....certainly worth the effort to build, even if they can't "run with the big boys".
AND.....I will give the guy on the JD forum credit for one of the Easiest, Simplest, and most utilitarian 2 bottom set ups I've ever seen on a small tractor.......down an dirty, but 100% functional and completely reverseable.....excellent application!!!!!
Bottom line on pulling 2 bottoms with a GT...if you build something big enough to be able to always run in the same furrow with the 10" and 12" plows, handle trash, etc. a std. sized GT won't have the a$$ to "handle" the plow....you might get it done, but you'll be on the edge the whole time......(and you won't be following any well set up 12" bottoms
....just ask Charlie
